fix: normalize Bosnia & Herzegovina and USA team name variants

Add TEAM_ALIASES to lib/wiki-scraper.ts applied at extraction time so both
scraper and sync consistently produce canonical names. Removes the duplicate
alias map from seed.ts in favour of the shared normalizeTeam() export.

Aliases added:
  Bosnia & Herzegovina  → Bosnia and Herzegovina
  USA                   → United States
